Các bạn cho mk hỏi
1) Cho 4x-3x =2 . Tính M =12x - 9x +5
2) Cho x+y =10 .Tính P = 2x+3y+5x+2y+8
3) Cho 4x-3y=2 . Tính M = 12x-9y+5
Tìm x biết:
1)3/4x-1/4=2(x-3)+1/4x
2)30%.x-x+5/6=1/3
3)(2.x-1).(3.x+9)=0
Tìm x biết :
1, 1/2x+2/3(x-1)=1/3
2, 4x-(3+5x)=14
3, x^2-4x=0
giải hộ mình mai mình nộp
x^2+2x=0
x^3-4x=0
3x+4x chia hết cho x+1
(2x+1).(y-3)= -10
1) 2( 3x + 5) - 6=0
2) 5x + 3 ( 4+ 2x ) = 25
3) 3 ( 4x + 1) +2 (x - 1) =105
4) 30- [ 2( x - 3 ) - 2 ] = 14
5) 3 ( x - 8 ) (4x + 5 ) - 8 ( x - 8 ) = 0
6) 4x = 8
tim x:
a, 3(2x+3)(3x-5)<0
b, 2x2 - 4x>0
c, 5(3x+1)(4x-3)>0
(2x-1/3)(3 1/2-1/4x)=0
